yeast infection! helppp

Okay so I'm only 15 and a virgin but I think I might have a yeast infection. I've been searching and I have all the symptoms except inflammation. Basically it's really itchy, I get a sticky white discharge ALL the time and it smell smells kinda bad. I don't have a mum and I have no idea what to say to my dad about it so what do I do and do I acctually have one?? Also if I went to see a doctor would they acctually have to look at my vagina?
